My inventiorn relates to improvements in vehicle chassis lubrication.

In' the luhrieetionof e. road vehicle chassis it has heretofore been a common practice to provide oil cups or grouse cups :tor

with lubricant 'adopted to .lisclnnfge to the Wearing ports. ln nniny instances the luhrb cont Iwits applied* directly to the 'wearing parts.' Lubrication has also been accomplished oy providing a lnhricentstorage redisposed in proximity to the engine, having a seperate comlnit lend ing therefrom to euch part. t0 he lubricated. A pump wnsprovided, driven either `from the engine or operated. manually, by ineens of which lnhricent'wns drawn from the stdroge receptacle nml forced. l leading to the respective cated.

The Inst-nemend system-wes highly experi parts to he lubrisivc and subject to considerable mechanical difficulty and breakage. The first-mentioned system, whichis in almost universal use, rs-

' quil-cs constant attention nml is, therefore,

, much neglected and productive ot' s greet i. such parts. This `struct'cil and operatively connected with the oLt snnoyzince,

provide luhricfnatwpumg'iing mcchcnism so mounted on the cassis of the road vehicle as to he operatively responsive to movement of the chassis produced 'by travel oi' .the vehicle over the rond. A pumping device may be associated witheech of a seiecteifl number of convenio tly and pivotally disposed springr shackles, which pumping device communi'- 'cetes with a plurality of parts vto he lulu-1- cntefl, which parts ere grouped shout the particular shackle to distribute -lnlnicnnt to pumping device is so conshiickle and n port to which the shackle is attached es to he operated by the'movemcnt of to the ports gronpe the shackle rclotiveto such pint to discharge lubricant under Vmessen, to 'the shackle and about thesliackle to be luhricctel. l

An important feature is the provision ol n l'nhl'izntntv distributing; device 'consistingot n. container for lubricant and un inlpeller ztssociated with u. slimzkle and a port 'to which the shackle is pivotcil to he actnetedby the movement of the shackle. relative s nch part euch partto he lubricated.

In l, I have indicated en automobile `chassis in plan having side freine -mcinhers i5 supported 'by wheels'l carried by axles ew of en automobile During travel of the vehicle over the road the spring shackles swing' about their pivotal connections with the *freine or springs and I make use oi this swinging movement to actuate suitable pumping mechanism which I provide in connection with eech one of a solected number of conveniently disposed shackles. This pumping prises n lubricant container anrl nn 'unpeller connected ,with the shackle to he cctncted by the nioveiicnt thereof.

' Rech slmclile,.using the terni in the'hroml 'general sense, comprises side members 20 connected et opposite ends by shackle bolts 21,

mechanism comv 'token 80 ed cou lings 26.

. toget er by a bolt which bolts are cored out at 24 to provide lubricant passagewa s. One of the side plates may be cored out i desired, as appears in Fig. 6,in dotted line,also indicated by the reference numeral 24, to provide a communicating passageway between the cored out passageways through the shackle bolts. I have shown these cored out passagewaysV as having outlets 25 leading to the Wearing surface of the bolts to lubricate the bolts.

My pumping device here shown is attached to one side of the shackle and secured to the ends of the two shackle bolts by screwthread- Eac pumping mechanism comprises end pieces 27 between which is supported a tubular section 28 and seating in annular recesses in opposite faces of the end pieces upon suitable askets 29. The two end pieces are held 30 which clamps the end ieces securely a ainst both ends of the tubuar section 28. Iave shown this container as -I consisting of a glass tubular section 28 encontainer.

.lubricant carrying receptacle and 1s of suit- A able size to Ais -has a discharge opening 38 ythe upper shackle bolt.

closed within a metal casing 3l cut away at 32 to indicate the lubricant content of the This tubular member serves as a carry the amount of lubricant desired.

My improved pumping mechanism comprises a pump chamber 33 which is formed in one of the end pieces 27 and communicates with the container by means of the passageway 34 to receive lubricant therefrom; A plunger 35 is disposed in the pump chamber' held outwardly by means of a spring 36 and a packing nut 37 is provided to make a tight ]oint with the plunger. This pump chamber normally closed by a check valve 39 held in position by a spring 40, which opening 38 leads to the secondary chamber 41. This chamber 4l has a discharge 42 through a suitable packing to the interior of the tubular coupling 2l; and therefrom to the passageway 24 in the shackle bolt,

In Fig. 9, I have shown, in section` u device such as illustrated in diagram in Fig. 5, in which the outlet from thc chamber 41 is by way of two branches one lending to each shackle bolt and in such construction a tube 43 leads from an outlet 44'lrom the chamber 4l. Thistube extends to the upper cnd piece 27 which is cored out at 45t() communicate with the tubular coupling 26 to carry lubricant to In this construction the passageway through each shackle bolt turns to "discharge at the outer wearing surfaccof the bolt and there is no return o'l the lubricant to the receptacle.

In Fig. 6,1 have shown in diagram u circulatingsystcni provided with outlets lor dischargeof hihricant, to the wearing parts and providing for the return of lubricant tothe container and the circulatiornof lubricant through the system, and in such construction Y vehicle over the road. In Figs. 3, 4, 8 and 11,

I show the lower end piece 37 providedV With an angular support 46 which serves as a bearing for a pin 47 to one end of which pin is Secured a lever arm 48, the outer end of which arm carries a roller 49 that 1s adapted to ride I. on the upper surface of the spring 18. 'On the opposite end of the pin 4i is 'mounted a lever arm 50 which with the lever arm 48 and the pin 47 forms what-corresponds to a bell crank lever. The lever arm`5() carries an adjustable stop A5l which impacts the end of the plunger 35 to drive the same inwardly against the resistance of spring 36. The swinging movement of the shackle produced by road travel of the vehicle 'causesthe spring 18 to rise and fall, which through the roller 49, lever arm 48, pin 47, lever arm 51, forces the plunger 35 inwardly against the resistance of spring 36, Therefore, the rise and fall of the spring produces a pum ing action which draws lubricant from t e' container into the pump chamber and forces it from the pump "chamber, past the ball and check valve 39 to parts to be lubricated. By this means it is possible to force lubricant to parts desired and to develop sufficient pressure to overcome resistance offered to the passagcof the lubricant by encrustation or fouling ot' the passageways through which the lubricant must flow.

I show vin Fig. struction for 7 a modified form of conproducing the pumping action.

50 and stop ln this construction lv pivot to the bracket 46 by means of a. pin a iever arni52. This lever arm is shown as extending above and below the pivot point. At thc lower end it is connected by link 54 with the traine member l5. Swinging movement of t e shackle causes thc lcvcr to oscillate about its .pivot point and opi-.rale the piston orplunger in Fig. ll, I have showna, second modified 'torni in which one of the side pieces 2O has been recessed at to provide a container for lubricant rwhich has a discharge lending to the pump chamber SVS ,The discharge from the pump chamber is l. .ftojfasecondary chamber 58 and from ythis secondary chamber through thesvstem ,as above described. The only diiicrrncc between this construction and the construction heretofore described is that an enlarged sid'e'i'iicce is provided which is cored out to fornia receptacle for lubricant. l have described my, invention as provided with lubricant passagcwavs leading to the parts of the shackle to which the device is uttaehedto luhricute the shackle. I have alii@ to adapt my form of lubricatiou'to lubricete 'zi 'Vehicle chassis mul attach vmy improved pumpingr mechanism 'to a selected number of suitably iocutccl shut-klee mul provide lubricating conduits lcetlihg' from the pump to the group of parte to be lubricated located in thc immediate vicinity of 'the lubriciitiu;a device.
